This Python module does not accept complex data types. The more complicated equivalent is the math module.
We can, for example, calculate all trigonometric ratios for any given angle using the built-in functions in the math
module. We must provide angles in radians to these trigonometric functions (sin, cos, tan, etc.). However, we are
accustomed to measuring angles in terms of degrees. The math module provides two methods to convert angles
from radians to degrees and vice versa.
Program code 2:

Here we give an example of a math module in Python for calculating the factorial of a number. The code is given
below -
1 import math

2 n=int(input())
3 print(math.factorial(n))
Output:
Now we compile the above code in Python, and after successful compilation, we run it. Then the output is given
below -

Python User Input
User Input
Python allows for user input.
That means we are able to ask the user for input.
The method is a bit different in Python 3.6 than Python 2.7.
Python 3.6 uses the input() method.

Python 2.7 uses the raw_input() method.
The following example asks for the username, and when you entered the username, it gets printed on the screen:
Python 3.6
username = input(“Enter username:”)

print(“Username is: “ + username)
OUTPUT
ENTER USERNAME:

How to Take Input from User in Python
Sometimes a developer might want to take user input at some point in the program. To do this Python provides
an input() function.
Syntax:
input(‘prompt’)
where prompt is an optional string that is displayed on the string at the time of taking input.
Example 1: Python get user input with a message
